Shadow,
Yes, you could have and probably should have done Barbarossa in Alpha 2 instead of Sea Lion, but given the better odds, many people went Sea Lion instead and ended up sapping the Strength of the Germans to the point that Russia became impossible.
Why are 24 infantry in the East better for Japan than 18? Because they are just infantry, and they are not preventing the Germans, unlike the 12 IPC were. Japan has 11 Fighters, 8 Tactical Bombers and 2 Strategic Bombers. That is almost 1 aircraft per infantry Russia has. The extra guys will also probably not come into play until the Russian stack is decimated either through direct attack or by killing the blitz blockers left behind as it retreats. I’d rather Russia get 6 infantry in the middle of no where than Russia get 12 IPC to use in directly blocking the Germans!
The limitations on Japan’s movement is probably a bad thing. I would wager heavily that Larry did this because he is very pro America, continually making it a behemoth in his games and now Japan had a way to take it out early in the game. By limiting Japan so they cannot get close to America/Central America, this tactic is removed. I think it’s bad, I liked threatening America and forcing them to both lose W. USA and build ground units. It was probably the only tactic that saved the Japanese from destruction. The fall back option just delays the Japanese destruction and the best option so far, in my opinion, is to send all the japanese planes deep into Russia and get them on the German stacks, then over to Europe where you can suicide them into the Allied fleets. (Leaves you very vulnerable in the Pacifc, but the first time I did this it really unbalanced things for the Allies and the Germans were victorious via victory cities.)
I didnt say Barbarossa was “amazing” I said the changes made Russia weaker in comparison to the Germans. If you only look at changes, then Germany got more added units than the Russians did. If you want to look at strategies, the Germans were buffed up considerably due to the AA Gun changes. It is now viable to risk your guns as a strategic move, instead of keeping them in reserve as a tactical decision on a round by round basis.
So to definitively answer the original question…Russia is Weaker now. Actually the entire Allied game is weaker now. The allies are in a vice, they have to send aid to Russia asap, or Russia will fall. A dedicated effort of all three axis powers destroy Russia about 8-12 rounds in, unless the Allies help them turtle.
